If a mod wants to move this to Other Reel Games they can. It was clearly a Bally at one point but not anymore.
Went through the whole machine. Reclad the cabinet, cleaned the inside and polished the chrome which is still pretty badly pitted. Was able to get a replacement coin head but the coin tray and door lock is missing. Need to check the bulbs but so far two sockets are broken and another two are loose. Voltages all seem good however.
It's got a pretty jank fluorescent light added under the belly display. There's already two lights under there so I dunno, there should be a black light in there?
Has one power supply in the back corner that delivers 5V for the CPU and some of the lamps. Tests good.
Reels needed a cleaning and the rubber plunger was still in the tube. Pulled that out and packed it with grease. Spins and stops fine now.
The CPU is still being unhappy. Sometimes it beeps. Sometimes a payline turns on but it doesn't respond to coin-in or spins. Poked around and the 5mhz crystal came off so that might be part of the problem. Both EEPROM's are fighting to cleanly dump. Even with cleaned legs both my programmers can't get consistent dumps. I got nothing to compare with and aside from rta76 and this thread -

Did also sit down and reverse engineered the CPU board. Very simple design. Aside form the EPROMs it's all easy to get parts.
